I wasn't sure what the converter was having to charge or not i did take a reading and it was a little over 13 volts at battery so I unhooked it. not being sure of batt. condition but then got to thinking that with no batt. hooked up will it try to keep charging? Anyways left unhooked last night and batt reading this morning is 13.3 volts but nothing has run off it all night. dont have my minn kota load tester on hand but that seems good been unhooked for about 14hrs now. I was reading voltage at a receptacle when ac was trying to cycle back on. It tends to surge and thermostat click after it runs a bit so I'm thinking that the unit is just getting hot. and the ems? on the unit is just not letting it run due to low voltage. or the compressor is going out do to past low voltage.
